SAFETY DELIVERY RECEPTACLE.

Application filed June 12, 1926 Serial No. 115,477.

This invention relates to safety delivery receptacles and has for oneobject to provide for the sanitary, safe and theft-proof storage ofbottles containing milk or cream.

Another object of this invention is to provide, in receptacles of theclass described, a means for the safe storage of empty milk or creambottles so as to permit the ready removal of same from said receptacle.

WVith the above and other objects in View, the invention consists of thecombination and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that, within thescope of what is claimed, changes in the precise embodiment oftheinvention shown can be made without departing from the spirit of theinvention.

In the drawing Figure 1 is an elevation in perspective of the invention;

Figure 2 is a side elevation with the wall removed;

Figure 3 is an elevation of the inside of the door. i

In the accompanying drawings a preferred form of my invention is shown,in which 1 refers to a cabinet of suitable material, preferably wood,and having one open side wherein is positioned the door 2 mounted on thehinges 3 to swing horizontally and having intermediate its free edge thekey hole 4 and on its inside face the lock 5 so as to coincide suitablywith the saidkeyhole, said lock having the lock bolt 6 which is causedto advance from its upper side by means usual to such locks suitably tomake contact with the right angularly projecting finger 7 of the upperarm of the bell crank 8, preferably constructed of a flat metal bar andhaving on its lower arm the right angularly projecting finger 9 shapedto form the hook 10 having an inclined or cam shaped face 11 thereonthat causes the said hook to automatically engage with the lip 16hereinafter described. The said bell crank 8 is rotatably mounted on thepin 12 affixed to the door 2, the said pin 12 being positioned to oneside of the center of gravity of the said bell crank 8 so as tocause thesaid bell crank to normally assume the position shown but free to rotateunder the influence of other agencies as hereinafter described- The sidewalls of the cabinet 1 have provided therein the holes 13 positionednear the bottom of said cabinet and between the center and the open sideof said cabinet, said holes having afiixed therein the rod 13. Restinguponthe rod 13 is the false bottom 14 constructed of a metal plate ofdimensions-slightly smaller than theinside of the said cabinet 1, andhaving formed thereon the lips 15 suitably positioned so as to confinethe said false bottom 14 against transverse movement relative to the rod13 but permitting the said false bottom 14 to be lifted vertically fromthe rod 13 and removed for cleaning. Also formed on the said falsebottom 14 is the lip 16 positioned intermediate the front edge thereof.

The said false bottom 14 is mounted in the said cabinet 1 so as to bepivoted nearer its frontedge than its back edge, as is obvious from theposition of the aforementioned rod 13. It is obvious that the said falsebottom 14 will incline rearwardly by the action of gravity; means forrestraining the pivoting motion of the said false bottom areprovided ashereinafter described, whereby the said false bottom will be caused totake a horizontal position by the weight of an article, such as the milkbottle 17, when the said article is placed on the said false bottomforwardly the said pivoting means or rod 13. When in the said horizontalposition the said false bottom co-operates with the before describedlocking means provided on the said door 2 so as to releasably latch thesaid door 2 to the said false bottom 14, as will now be described.

When a bottle 17 containing milk or cream is placed on-the falsebottom'14 so as to be positioned outwardly from the rod 13, the weightof the saidbottle 17 causes the false bottom 14 to rotate about the rod13 so as to take a horizontal position, said rotation being restrainedby the engagement of the inside edge of the said false bottom 14 withthe right angularly projecting finger 18 of the stop 19 aflixed to theinside of the rear wall of the cabinet 1. Vhen the said false bottom 14is in a horizontal position as above described and the door 2 is closedthe lip 16 engages with the cam shaped face 11 thereby causing the bellcrank 8 to rotate about the pin 12 so as to permit the hook 10 to latchunder the lip 16 thereby causing the door 2 to be held in a closedposition, but when the bolt 6 of the lock 5 is caused'to advanceupwardly by means usual to sucn locks,

the said bolt 6 will engage the finger 7 thereby causing the bell crank8 to rotate about the pin 12 so as to unlatch the hook 10 from the lip16 thereby permitting the door 2 to be opened and the bottle 17 removedfrom the receptacle. The false bottom 14 will then rotate about the rod13 so as to take a position inclined rearwardly, said rotation beingrestrained by the engagement of the inside edge of the false bottom 14with the floor of the said cabinet 1 thereby causing the lip 16 to movevertically upward 350 as to be pre vented from engaging the hook 10 whenthe saidhook 10 is returned to its normal posi tion. \Vhen empty bottlesare placed in the receptacle they should be positioned on the falsebottom 14: so as to be rearward of the rod 13 thus permittingthesaidfalse bottom 14 to remain in a rearwardly inclined position. When thebolt 6 is caused to be withdrawn into the lock 43, thus permitting theball crank 8 to return to its normal position it islohvious that thehook 10 will not engage the lip 16 and latch the door 2 until thefalsewhottom 14 is caused to take a. horizontal position in the mannerheretofore described. :The rear wallet the cabinet 1 has providedthereinthe holes 20 whereby the receptacle may be supported on a wall orotherwise as desired. Also is provided the knob .21 positionedintermediate the free edge of the door 2 and on the outside thereof forconvenience in opening said door.

For convenience in description and illustration I have shown theinvention carried forth with a cabinet of wood andfittings andappurtenances oi metal; however, it is obvious that the invention 1s notlimited 1n practice to such materials but may be also constructedentirely of metal.

I claim:

In a device of the kind described, the combination with a cabinet, adoor hingedly mounted on the said cabinet, and a false bottom pivoted inthe said cabinet, of a locking means conn n-ising a lock; a lock boltprovided in the said lock and ada ted to advance upwardly from the saidock; a bell crank pivoted on the said door; a right angiiilarlyprojecting finger provided on the upper arm of the said bell crank; thesaid projecting finger being adapted to engage the said lock bolt whenthe said lock bolt is advanced upwardly from the said lock; a rightangularly projecting finger provided on the lower arm of the said bellcrank; an inclined or cam shaped face provided on the second mentionediro'ectin fin er so as to a form a hook; a downwardly projecting lippositioned on the forward edge of the said false bottom; the said lipbein adapted to engage the said hook whereby m said door may be latchedto the said false bottom.

In testimony whereof I atiix my signature.

CHARLES E. HOFFMAN.
